What are those amazon approved earbuds that has a mic for phone calls?

I have seen the list of approved by amazon earphones but none of them seem to have mic support for phone calls. However, I've seen quite a few people at my location using what earphones with the dark greyish-blackish wire instead of the orange/yellow ones and it seems that those particular models allow you to make phonecalls. Does anyone know the exact model for those and could link me to them?
